Review. The evolution of research regarding the economics of irrigation water

This work analyses the main research trends (subjects, methodology used, countries of the authors and data) in the economics of irrigation water during the last 10 years (2000-2009). For this purpose, a quantitative methodology has been used which is new to this sphere, based on the review of a representative sample of 332 papers published in the 15 most important journals focused on this field of science indexed in the databases of the Institute for Scientific Information (ISI), the Science Citation Index (SCI) and the Social Science Citation Index (SCCI). The results obtained confirm: a) the notable growth in the number of papers published, especially in the last three years, b) the high degree of collaboration between authors, including those of different origin, for their performance c) the prominence of the USA, Australia, India and Spain as the countries of the first authors and origin of the data, d) the greater attention given to subjects related with «investment project analysis», «production planning» and, especially, «production function and productivity of water», and e) the predominance of empirical studies that use basic analysis approaches (cost analysis, investment evaluation, etc.).El presente trabajo analiza las principales tendencias de investigación (temáticas, metodologías utilizadas, países de los autores y de los datos) en economía del agua de riego en los últimos 10 años (2000-2009). Para ello, se ha utilizado una metodología cuantitativa, novedosa en este ámbito, basada en la revisión de una muestra representativa de 332 artículos publicados en las 15 revistas más importantes en este ámbito científico, indexadas en las bases de datos del Institute for Scientific Information (ISI), el Science Citation Index (SCI) y el Social Science Citation Index (SCCI). Los resultados obtenidos confirman: a) el notable crecimiento del número de artículos publicados, sobre todo, en los tres últimos años, b) la elevada colaboración entre los autores para su realización, incluso de diferente procedencia, c) el protagonismo de EEUU, Australia, India y España como países de los primeros autores y de procedencia de los datos, d) la mayor atención prestada a los temas relacionados con el «análisis de proyectos de inversión», la «planificación de la producción» y, especialmente, a las «funciones de producción y la productividad del agua», y e) el predominio de los trabajos empíricos que utilizan técnicas de análisis básicas (análisis de costes, evaluación de inversiones, etc.)

Tagging and recapture activities carried out by the Spanish Confederation of Responsible Recreational fishing (ceprr) with the Scientific Coordination of the Spanish Institute of Oceanography (IEO) in the Mediterranean (2008-2011)

During the 2008-2011 period, 1548 specimens of tuna and tuna-like species were tagged by the Spanish Confederation of Responsible Recreational Fishing (CEPRR) with the scientific coordination of the Spanish Institute of Oceanography (IEO). Of these, 1031 bluefin tuna were tagged with conventional tags, whereas 10 other specimens of the same species were tagged with pop-up satellite electronic tags in the Mediterranean. Five pop-up electronic tags remained on the adult specimens up to 110 days. In this period, the specimens stayed in the tagging area except for one of them, which reached Algerian waters in the winter. Similarly, 333 long-finned tuna and up to 184 specimens belonging to other species such as swordfish, little tunny, bonito, frigate tuna and spearfish, were also tagged. Eight bluefin tuna were recaptured, including one adult tuna which was found in the same area where it was tagged (Balearic Islands) 1343 days after release. A juvenile tuna tagged in the Mediterranean was recaptured more than two years after release in the Cantabrian Sea. Over the 2008-2011 period, the IEO provided a number of training courses on conventional and electronic tagging techniques at the different ports where tournaments and/or tagging and release campaigns were carried out. This promoted participation of the CEPRR in the tagging design of the GBYP-ICCAT Atlantic-wide Research Programme on Bluefin Tuna, as well as strategic and scientific interest.Postprin

Tumores óseos de la pelvis

Se presenta la experiencia del Servicio de Ortopedia del Adulto del Hospital «Ramón y Cajal», en neoplasias de la pelvis, desde su creación hasta la actualidad, siendo 61 los pacientes recogidos y no se hace un trabajo estadístico, sino más bien se muestran las peculiaridades recogidas con la experiencia, que abarca desde la abstención en algunos casos de tumores secundarios, y el simple curetage hasta las grandes sustituciones con homoinjertos de banco, relacionándolo a su vez con publicaciones de aparición más o menos moderna sobre este tema, para concluir que se trata de una cirugía no exenta de complicaciones y problemas, pero necesaria a la hora de proporcionar a los enfermos curaciones, que le ofrezcan una salida a este difícil problema.The experience of Adult Orthopaedics Unit at the Hospital «Ramón y Cajal», Madrid, treating patients with malignant tumors of the pelvic bons is presented. In this paper, the results after surgery are not reported in terms of statistical analysis. The aún of this work is to comment the surgical experience covering from simple curettage to great bone replacement using bank allografts. The message is that surgical treatment of pelvic tumors is not exent of complications, but it seems to be worth in order to offer a better quality of Ufe for patients

Análisis de los resultados de las Campañas de marcado de Atún rojo (Thunnus thynnus) del “Tagging GBYP-ICCAT 3ª Fase realizadas en el Golfo de León y Estrecho de Gibraltar durante 2011-12

In the Gulf of Lion Campaign 109 bluefin were tagged with conventional tags measuring between 74 cm and 108 cm fork length (LH). Five of these specimens had an electronic mark mini-patt placed on them. The campaign of the Strait of Gibraltar took place from 5/10/12 to 21/11/12 with 117 days at sea with a total of 1,477 bluefin marked of which 1,432 copies were marked, mainly with a double mainstream brand mark, 20 individuals with an electronic type pop-up (mini-pat) and 25 more fish with internal electronic tags. The tagged fish measured between 70 cm and 130 cm fork length (LH). Likewise, the biological samples which were scheduled were obtained for more than 40 samples of bluefin tuna of all sizes.Postprin

Campañas de marcado de atún rojo juvenil (Thunnus thynnus) juvenil coordinadas por el IEO, previstas en el Programa ICCAT-GBYP y realizadas en el Estrecho de Gibraltar durante Noviembre de 2011 y enero de 2012

This paper presents the results of conventional tagging surveys on juvenile bluefin tuna conducted in the Strait of Gibraltar during different periods of 2011 and 2012 with two vessels from the port of Algeciras that usually fish using pole and bait in that area. The campaigns were carried out within the framework of the Enhanced Research Program for Bluefin Tuna (Thunnus thynnus) (GBYP). In 36 days of activity, a total of 1389 bluefin tuna were tagged, weighing an average of approximately 15 kg, ranging between 7 and 40 kg. In 46% of the specimens, two different tags were placed, and the forecasts established in the Tagging Plan within the ICCAT-GBYP were achieved.GBYP-ICCATPostprin

Molecular features in a biphenotypic small cell sarcoma with neuroectodermal and muscle differentiation

We report a case of a 13-year-old girl with soft tissue sarcoma of the hand, which showed muscle and neuroectodermal immunophenotypes. Molecular studies were performed on RNA collected from fine-needle aspiration (FNA) cytology and peripheral blood samples by nested reverse transcriptase-polymerase chain reaction (RT-PCR) and Southern blot analysis. This biphenotypic tumor showed simultaneous expression of EWS-FLI1 and PAX3-FKHR transcripts, specific of Ewing family tumors and alveolar rhabdomyosarcoma, respectively. Although childhood sarcomas with simultaneous muscle and neural differentiation have been described to have EWS-FLI1 transcripts, there are no reports of tumors with both transcripts. Cytological specimens are a good source of RNA for molecular studie

El atún blanco (Thunnus alalunga) del Mediterráneo occidental

The situation of the Spanish fishery of albacore (Thunnus alalunga) in the western Mediterranean during the last years is presented. Catch data, fishing effort, CPUEs and size distributions are presented by gear and spatial-time strata. The mean annual catch of albacore in the last ten years reaches 310 MT, which makes a temporary alternative fishing method to the longline fisheries of swordfish. The finding of spawning areas around the Balearic Islands and the information from CPUE analyses by strata, in the future, could contribute, from a qualitative point of view, to important biological information of the species in the western Mediterranean.Le présent document fait état de la situation de la pêcherie espagnole de germon (Thunnus alalunga) dans l’ouest de la Méditerranée au cours de ces dernières années. Les données de capture, l’effort de pêche, les CPUE et les distributions de tailles sont présentés par engin et par strate spatio-temporelle. La capture annuelle moyenne du germon ces dix dernières années a atteint 310 t, ce qui offre aux pêcheries palangrières d’espadon une alternative temporaire. L’existence de zones de frai autour des îles Baléares et l’information que fourniront les futures analyses de CPUE par strate spatio-temporelle et par engin de pêche pourraient apporter, d’un point de vue qualitatif, d’importantes informations biologiques sur l’espèce dans l’ouest de la Méditerranée.Se expone la situación de la pesquería española del atún blanco (Thunnus alalunga) durante los últimos años en el Mediterráneo Occidental. Se presentan datos de captura, esfuerzo, CPUEs y distribuciones de tallas por arte y estrato espacio-temporal. La captura media anual de atún blanco para los últimos diez años alcanza las 310 Tm., lo que supone una alternativa temporal a la pesca de pez espada con palangre de superficie. La existencia de áreas de reproducción en torno al archipiélago Balear, unido a la información aportada por futuros análisis de CPUE por estrato espacio-temporal y arte de pesca, podrían aportar, desde el punto de vista cualitativo, importante información biológica sobre la especie en el Mediterráneo Occidental

Resultados de la encomienda de la SGP al IEO para el estudio del atún rojo (Thunnus thynnus) del stock del Atlántico este (que incluye el Mediterráneo) considerando las almadrabas españolas como observatorios científicos

During the years of 2010-2012 was a research project bluefin tuna traps using Spanish as scientific laboratories. The main objective was to keep the knowledge of the tendency of the index of abundance of bluefin tuna caught with these nets, and it is the most significant index used in the stock assessment process East Atlantic, including the Mediterranean. Likewise studies were developed bluefin tuna biological parameters such as growth, feeding, reproduction, stock structure and migration patterns, the results provide an important advance in the understanding of the biology and behavior of this species.Versión del edito

STANDARDIZED CATCH RATES FOR MEDITERRANEAN SWORDFISH (XIPHIAS GLADIUS LINNAEUS, 1758) FROM THE SPANISH LONGLINE FISHERY. 1988-2018

Standardized relative abundance indices for swordfish (Xiphias gladius Linnaeus, 1758) caught by the Spanish surface longline in the western Mediterranean Sea were estimated for the period 1988-2018. Standardized CPUEs in number were estimated through a General Linear Mixed Modeling (GLMM) approach under a negative binomial (NB) error distribution assumption. Standardized CPUEs in biomass were estimated through a General Linear Mixed Modeling (GLMM) approach under a log-normal error distribution assumption. The main factors in the standardization analysis were fishing area and time of the year (quarter). The standardized indices showed notable annual fluctuations without any definite trend for the period under studyEn prens
